From Sanskrit लय laya, "mental inactivity, rest, repose, dissolution."
"Laya Yoga is Kundalini Yoga. Concentration on the sound emanating from the heart-lotus is Laya Yoga. Laya is dissolution. The mind is dissolved in God just as a lump of ice is dissolved in a tumbler of soda-water." - Swami Sivananda
"The Hindu esoteric school of Laya Yoga with its famous Laya-Kriya Tantric sadhana is marvelous, by all means, and leads the neophytes to the realization of the Innermost Self." - Samael Aun Weor
